My screen keeps dimming on a HP Pavilion computer g laptop with Windows 7, why?
Even if I'm on the internet, my screen fades at random, according to the Web site. Sometimes he would go to normal brightness and then right back to really dim. It would get so dark that I could hardly read anything on the screen in a dark room. I can't adjust the brightness with the F2 and F3 keys and I tried to adjust the brightness of the power management, and nothing changes. How can I keep the screen from dimming all the time?
Your video card was built by AMD/ATI?
If so, the Vari-Bright feature must be on. To fix this, go to:
1 AMD Vision Engine Control Center (or AMD Catalyst Control Center)
2 power
3 PowerPlay
4. uncheck the ' enable Vari-Bright ".
and that will fix your problem.

Recently bought studio 15 laptop with windows 7 and I try to run need for speed pc underground game on her, but she does not appear and the message "speed.exe has stopped working" appears on the screen. can someone help us?
Hi Andy,.
I checked the reported compatibility list, and the game is listed as compatible. Work in 64-bit or 32-bit Windows 7? I will try to reinstall the game, if you did an upgrade from Vista to Windows 7 recently. If it is a new installation and does not, please visit the EA's Web site to get the latest patch for the game to see if that helps address your problem. Let me know if you've done all that and you still have questions, and we can try something else.

We try to use Adobe Photoshop Lightroom 4 on a new laptop with Windows 10. Everything on the screen was to small to use. I got the picture to the center of the enlarged screen, but the words on the side of the screen are still too small to read

Hi Tanuj,
There is no place to change fonts.
You must go to the LR Edit (or Lightroom on Mac) menu > Preferences > Interface > choose 'Options' in the menu 'panels '. There should be a setting for the font size of Interface. You will need to close and restart LR for the font change are taken into account.

My screen keeps dimming every few seconds, even if I changed the settings and saved!
Hi I have Windows 7 and I have passed to the control panel and changed the settings for power. I got my high-performance switch mode, changed the settings so that it only fades every 10 minutes and saved. However, my computer keeps dimming of the screen at very low about every 7 seconds! I have to make it brighter, but it fades again! Sometimes it fades it right after she cheer up! I even tried to make a personalized plan, but it did not work. What can I do to make the screen stop all seconds dimming! I've tried everything!
You are using a laptop computer monitor or a desktop monitor / external? This is much like a monitor that has its own management food or, as with many TVs, the ability to change the brightness in response to changes in ambient light levels.

black screen no beeps or messages on laptop with Windows 8 o he
Hello
1. I had a laptop computer of a person who had the power led, wifi turned on, the battery on but no light on HD LED. the screen was all black whitout messages, I have attached the laptop screen nested to be sure that the screen was not damaged. but on extern screen the laptop screen was still dead. so I didn't know that the screen was not the problem, the only thing I thouthg to replace HD with nested one (of the same type) so I did but problem stiil exist. What can be the problem, black screen whitout any beeps or any message, all LIGHTS are lighthing in addition to HD LED,.
a friend of mine who worked 25 years in the information technology Department told me that the problem can the bios, or some bad update of the bios.
But what you do the thing, can memory cause such a problem.
THA laptop is ASUS X501A with windows 8 on it.
I do not call ASUS I myself work with computers.
Thank you
Johan
It could be the BIOS, but I bet it's more likely that the video card is broken and no longer send any signal. A BIOS would have normally caused a beep or something.

ITunes screen keeps flashing on and off since the last update on windows PC.
Hi, since the latest itunes update, my screen flashes on and off whenever I am in itunes. ITunes crashes regularly. I am able to download music without problem. The flashing light does not occur when I'm in my own music, just at the moment when I am on itunes. Any suggestions? Thanks for the help!
Download iTunes from http://www.apple.com/itunes/download/ 12.3.2.35 and reinstall. Apple have eliminated a update in the last 24 hours (which very badly, they identified as a separate release or generation) which sets store flashing screen which affect the initial version (9 December) of 12.3.2.35.

HP Pavilion 15
Product no.: P3C83PA
Edition: Windows 10 home
System: 64 - bit
Kind regards
Sonia McMahonI wish I had some good news for you, but I did not...
It seems that the screen has turned off, at least while it runs Windows.
About all you can do is that this point is to try to run some diagnostics incorporated - since the PC does not have Windows for those, I hope that the display will work.
Turn off your laptop, restart and continue to press F2 until you get a menu on screen or it starts to beep.
When the menu is displayed, choose the option run diagnostic - and report what is happening after that.
Good luck
